Brief Overview and Advantages
The Fenix BC05R V2.0 bike light is an updated version of a popular model with improved brightness, runtime, and a wider viewing angle. Compared to its predecessor, the light offers +50% brightness, +67% runtime, and the viewing angle has increased from 120° to 180°, significantly enhancing cyclist visibility from behind. The maximum light output is 15 lumens, the illumination angle is 180°, and the beam distance is up to 50 meters. The light is also visible from a distance of up to 230 meters, thanks to five LEDs that produce red light.
Detailed Description
The model's body is made of durable plastic, providing IP66 water resistance and withstanding drops from 1.5 m. The dimensions are compact — 51×22×22 mm, and the weight is indicated in two places: in the table — 19 g including the battery, but the description also mentions a value of 28 g. The light has a universal mounting strap that fits seat posts with a diameter of 20–35 mm, and the clip allows it to be used as a chest or backpack light.
Power and Charging
Power is provided by a built-in 400 mAh lithium-polymer battery. A full charge via USB Type-C takes approximately one and a half hours. The light is equipped with a charge indicator: when the switch is pressed while off, the indicator will show the battery status for 3 seconds — a steady green light means 100%–85%, flashing green — 85%–50%, steady red — 50%–25%, flashing red — 25%–0%. There is a low voltage alert function: when the voltage drops below 25%, the indicator glows red, and the light will continue to operate until the battery is fully discharged.
Operating Modes and Intensities
The light has six brightness modes and several flashing options. Switching is done with a single button on the body. The sequence of modes when on is: Low → Low Flash (slow) → Low Flash (fast) → High → High Flash (slow) → High Flash (fast).
- Low: 5 lumens, runtime — 16 hours, intensity ≈ 3 candelas.
- Low Flash (slow): 5 lumens, runtime — 80 hours, intensity ≈ 3 candelas.
- Low Flash (fast): 5 lumens, runtime — 120 hours, intensity ≈ 3 candelas.
- High: 15 lumens, runtime — 4.5 hours, intensity ≈ 9 candelas.
- High Flash (slow): 15 lumens, runtime — 25 hours, intensity ≈ 9 candelas.
- High Flash (fast): 15 lumens, runtime — 35 hours, intensity ≈ 9 candelas.
